Nichols, Fries, Va., assignors to Mystik Adhesive Products, Chicago, 111., a corporation of Illinois Filed Nov. 29, 1956, Ser. No. 625,091 13 Claims. (Cl. 28-32) This invention relates in general to a warp beaming method and an apparatus therefor as more particularly described as a method and apparatus adapted to engage and hold a warp of yarn or thread and to tape ends in taking off a full beam or dividing it into separated parts.

When the winding operation in preparing a beam of yam is completed, means is provided for retaining and holding the adjacent ends of yarns of the warp in their proper spaced relation when the threads are cut and packaged for separate use or shipment. This is commonly effected by applying adhesive strips on opposite sides of the warp extending across the full Width thereof. When the warp is unwound from a beam by the customer, all of the warp threads are separated and maintained in place for use by a customer.

In the past, this taping has been a tedious and time consuming manual operation in quickly and accurately applying the tape across the warp at the cut ends to maintain the strand pattern.

An important object of the present invention is to provide an improved novel apparatus and a method for applying tape across the width of the warp.

A further object of the invention is to provide an apparatus operable from one side of the warp for projecting a tape transversely thereof to the other side.

A still further object of the invention is to provide power apparatus for projecting a fastening tape across the warp of threads to be connected.

Other objects of the invention will appear in the speci fication and are apparent from the accompanying drawings in which,

FIG. -1 is a perspective view of a warp beaming apparatus for carrying out an improved method of leasing in accordance with this invention.

FIG. 2 is a perspective view of the right end of the apparatus shown in FIG. 1 in a tape raising position.

FIG. 3 is a perspective view of the left end of the apparatus shown in FIG. 1 with an operating motor instead of a manual crank.

FIG. 4 is an elevational view of the apparatus in FIG. 1 illustrating the operation thereof.

FIG. 5 is a sectional view of the apparatus in an operating position as shown on the line 55 of FIG. 4.

FIG. 6 is a somewhat diagrammatic view showing the method of applying a tape to the under side of the warp.

FIGS. 7, 8, 9 and 10 are somewhat diagrammatic views illustrating the application of tapes at one and both sides of the warp.

FIG. 11 is a fragmentary view illustrating one method of connecting the warp threads by two sets of tapes and cutting between them; and

FIG. 12 is a fragmentary view illustrating the application of a single set of tapes to opposite sides of a warp and cutting lengthwise through the tapes to sever the warp.

This invention comprises a belt device which extends transversely under the full width of the warp having means for operating the belt and a pick-up to engage a tape for moving it from one side to the other with means for bodily moving the tape in contact with the warp threads and adhesively binding the warp threads in spaced relation by one or more strips of tape at any desired location for facilitating the cutting of the warp threads and maintaining them in proper relative positions.

Referring now more particularly to the drawings, a plurality of warp yarns or threads A are represented in FIG. 6 as passing about guide rods B and C and over a space guide rod D. In order to maintain the warp threads in their relative position transversely of the beam and for securing the ends of cut threads together, an adhesive tape 10 as shown in FIG. 7 is applied to the under side of the warp threads by means of a movable belt 12 and a pressure bar 14 as represented in FIG. 6. Either before or after the adhesive 10 is applied at the bottom of the warp threads, an upper adhesive tape 16 may be applied over the top of the threads as shown in FIG. 8 and compressed thereon as represented in FIG. 9, the compres sion of the two together being against the belt 10 backed by the pressure bar 14 when in raised position, holding the belt against the under side of the warp threads and shown withdrawn therefrom in FIG. 10.

With the adhesive tapes applied in this manner, two pairs of adhesive tapes 10 and 16 may be applied transversely of the warp threads A at a relatively close distance so that the threads between the two sets of tapes may be cut transversely .of the threads as represented in FIG. 11, thus binding the adjacent warp yarn or thread extremities together for subsequent use.

As shown in FIG. 12, a single set of tapes 10 and 16 may be applied above and below the warp threads A and a cut may be made longitudinally and centrally of the tape so that the cut ends of the tape will be adjacent the extremities of the cut threads.

To project an adhesive tape 10 below a web of warp threads which may be of considerable width, the belt 10 is mounted at its ends for reciprocating movement upon pulleys 18 and 20. One of the pulleys 18 is mounted uporra supporting frame 22 at one side of the web and the other pulley 20 is mounted upon a supporting frame 24 at the other side of the web. These two frames are accurately spaced apart and held in any adjusted position by a rod 26 adjustably secured at its ends in bearings 28 and 30 by said screws 32 adjustable in the top thereof. The supporting frames 22 and 24 are also adjustably mounted at the sides of a warp beaming apparatus to which it is applied by said screws 34 adjustable in slots 36 adapted to be inserted into a suitable supporting part of the beaming apparatus.

With the belt and pulleys thus mounted and spaced apart at opposite sides of the warp web, a gear 38 is secured to one of the pulleys 18 and has a driving pinion 40 engaging the gear for rotating it in opposite directions. This movement may be effected manually by means of a crank 42 secured to the pinion or by means of an electric motor 44 and a reduction gear connected to the pinion as shown in FIG. 3.

In projecting the tape 10 below the warp web, a fastening clip 48 is attached to the belt and is adapted to engage the end of a strip of tape 10 and to draw it from a roll 50 of the tape mounted upon a pin 52 projecting from a standard 54 extending upwarly from the supporting frame 22. The end of the tape is gripped by the clip 48 and the belt is moved by the gear and pinion connected to the roller 18 to loosen the tape from the roll 50 and to carry the tape with its protected (non adhesive) side downwardly across to the other side of the web on top of the pressure bar 14 which extends from one supporting frame to the other.

At the upper end of the standard 54 is another roll of tape 56 mounted for rotation upon a pin 58 secured to the standard and a strip 16 of this tape is easily carried over the top of the warp web to the opposite side thereof. This length of tape is pulled from the roll 56 and inverted so that the adhesive side is downward so that when applied over the warp threads and pressed downwardly against them opposite the tape 10, the threads will be sealed together between the tapes and 16 as represented in FIGS. 9 and 10.

In order to mount and apply the pressure bar 14, it is provided at each end with a guide pin 60 which extends through a suitable hole 62 in the supporting frames 22 and 24 for guiding it in an up and down movement, between and under the upper reach of the belt 12.

One end of the pressure bar 14 is engaged at its under side by a roller 64 mounted in a lever 66 upon a pivot 68 intermediate its ends secured in the frame 22. The other end of the lever is connected by a link 70 with one end of a similar lever 72 having a pivot 74 intermediate its ends supported by the frame 24 and with a roller 76 at the other end of the lever which engages the under side of the adjacent end of the pressure bar 14.

Connected to the link 70 at one end thereof and shown as connected to the end opposite the crank 42 is a lever 78 having a handle 80 at one end, mounted upon a pivot 82 intermediate its ends, the pivot supported by an upright standard 84 secured to the frame 24 and having its lower end connected by a pivot 86 with one end of a link 88, the other end of which is connected by a pivot 90 with the adjacent end of the connecting link 70.

The handle operating lever 78 is movable from an upright position as shown in full lines in FIGS. 1 and 4 in which case the rollers 64 and 76 at the under side of the pressure bar 14 are in their lowermost positions to an inclined position as indicated in broken outline in FIG. 4 and in full lines in FIG. 2 in which the rollers 64 and 76 are in their raised position engaging and elevating the upper reach of the belt 12 to slightly distort or extend the belt as shown in FIG. 2 so that the belt and any tape 10 thereon will be pressed against the under side of the warp threads and thereby to adhesively secure them together in spaced relation. 7

After the lower length of tape 10 is thus forcibly applied at the bottom of the warp strands, a length of tape 16 is manually drawn from the upper roll 56. This length of tape is inverted so that the adhesive side is turned downwardly and the upper tape 16 is pressed against the warp strands and against the lower tape 10 so that the strands are adhesively secured tightly between the lower and upper adhesive tapes.

If it is desired to cut the warp threads to separate one length of the warp from another, two sets of tapes may be applied as shown in FIG. 11 with a transverse out between them or a single tape may be applied as shown in FIG. 12 and a cut is made longitudinally and centrally of the tapes to secure the ends of the opposite warp strands together.

If desired, the pressure bar raising lever 78 may also be located at the same end as the belt operating means where it would be connected and operated in the same manner, but for clearness it is shown mounted at the opposite end of the belt and the link 88 and preferably extends through a slot 92 in the frame to confine the parts in place and to limit their operative movement.

With this construction, the tape is projected manually or by means of a motor which would operate in both directions to move the fastening clip 48 which is preferably secured to the belt 12 in one direction to project the tape 10 to the opposite side of the warp. The tape may be disengaged from the fastening clip 48 either before or after the tape is applied to the under side of the warp threads, the fastening clip 48 being ordinarily positioned beyond the end of the pressure bar or beyond the edge of the warp if it does not extend the full length of the bar. This construction is thus operated by power to project the adhesive tape across underneath a web in a quick and efficient manner so that a number of individual sections of the warp may be cut from a larger length thereof and the extremities of the warp threads quickly and securely fastened together for far:

4 ther individual actions and operation upon the warp sections.

While the method and a preferred construction for carrying out the method have been described in some detail, it should be regarded by way of illustration and example rather than a restriction or limitation thereof, as changes in the method and in the construction, combination and arrangement of the parts may be made without departing from the spirit and scope of the invention.
